Astra Linux – Vulnerability in sudo

In Sudo version 1.8.29, the fact that a user has been blocked for example, by using the “!” character in the shadow file instead of a password hash was not taken into consideration. This allows an attacker who has access to a Runas ALL sudoer account to impersonate any blocked user. NOTE: The...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: brnetfilter: do not check the confirmed bit in brnflocalin after confirmation. When sending a broadcast packet to a tap device, which is added to a bridge, the brnflocalin function is called to confirm the conntrack. I...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ftrace: Clean up the hash of directfunctions in case of register failures. The following GPF errors occur when registerftracedirect fails: General protection fault, likely for non-canonical addresses \ 0x200000000000010: 0000 ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: vxlan: Fixed the nexthop hash size. The nexthop code expects a 31-bit hash, such as the one returned by fibmultipathhash and rt6multipathhash. Passing a 32-bit hash returned by skbgethash can lead to issues, especially when th...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: The “binding mark” of a reused connection was unset. Steve French reported a null pointer dereference error from the sha256 lib. The cifs.ko module can send session setup requests using a reused connection. If a reused...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipv4: iptunnel: Fixed a suspicious RCU usage warning in iptunnelfind The per-netns IP tunnel hash table is protected by the RTNL mutex, and iptunnelfind is only called from the control path where the mutex is acquired. Added a...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed 0x432A9843 for all JSON object hash table operations. This allowed attackers to precompute key collisions offline. By providing a crafted JSON...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: The issue related to “slab-use-after-free” in smb3preauthhashrsp has been fixed. The function ksmbdusersessionput should be called under smb3preauthhashrsp. This will prevent freeing a session before calling...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ima: fixed the buffer overflow in imaeventdigestinitcommon The function imaeventdigestinit calls imaeventdigestinitcommon, with HASHALGOLAST being used to access the array hashdigestsize. This leads to a buffer overflow. A...

Astra Linux – Vulnerability in Linux

In the IPv6 implementation in the Linux kernel before 5.13.3, the net/ipv6/outputcore.c file has an information leak due to certain uses of a hash table. This hash table is large, but it does not properly take into account that IPv6-based attackers can typically choose from many IPv6 source...

Astra Linux – Vulnerability in libxml2

A issue was discovered in libxml2 before version 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logical errors. In one case, a double-free can occur...
